Polyimide, resin film and metal clad laminate
A resin film, in which at least one of polyimide layers is a non-thermoplastic polyimide layer having a linear thermal expansion coefficient of 1×10−6 to 30×10−6 (1/K), is shown. The non-thermoplastic polyimide layer is composed of a polyimide which is produced by reacting an anhydride component con...

Summary: | A resin film, in which at least one of polyimide layers is a non-thermoplastic polyimide layer having a linear thermal expansion coefficient of 1×10−6 to 30×10−6 (1/K), is shown. The non-thermoplastic polyimide layer is composed of a polyimide which is produced by reacting an anhydride component containing an aromatic tetracarboxylic anhydride with a diamine component, wherein the diamine component contains both a dimer acid-type diamine produced by replacing each of two terminal carboxyl groups in a dimer acid with a primary aminomethyl or amino group and an aromatic diamine, and the dimer acid-type diamine is contained in an amount of 1 to 15 mol % relative to the whole diamine component. |
